In the ai-eoinpanying drawings which form part of this specification, Figure l illustrates one emhodiment'of the invention. Fig. 2 is a vertieal seelional View of the apper end of one of the vertical shafts which carry the lifting aml balancing devices. Fig. 3, is a similar sectional view of the lower end of one of said shaltsi. Fig. l is a plan "View of a. part of one of the lifting devices.

The open frame work 1 .is oi any sniliahle construction adapted for these. purposes. Said frame work supports, prefe'nhly near the middle part thereof. a power or driving mechanism 2 which is arranged to rotate the shafts 8 extending toward the ends of the machine. One ol sairl shafts earries a propeller wherehy the n'larhine will he driven through the air. To each of :he shafts 3 a ;rear wheel is attar-hoil, saii'l gears being enmesheil with gm: 's 6 on the lower ends of the hollow oi lnhnlar rrrliieal shafts 7, lherehy rousing saii'l shafts to he rotate l when the power meehanisi'n in Specification of Letters; Patent.
